UNITED STATES JULIEN PIETERS, OF PARIS, FRANCE,

DISCHARGING DEVICE FOR VERTICAL RETORTS.

Application filed'July 1,

To all whom it may concern:

c by its blocking Be it known that I, JULIEN Pmrnns, a subject of the Kin of Belgium, and a resident of 12 Rue de it Rochefoucauld, Paris, France, have invented new and useful Improvements in Discharging Devices for Vertical Retorts, of which the following is a specification.

The French Patent No. 484,492 dated February 16th, 1917, describes an apparatus for the automatic discharge or drawing of the ovens in vertical continuous retorts.

The present invention relates to an apparatus for actual retention of the coke or other material resulting from distillation in avertical continuous retort. The material, instead of being directly supported at the bottom of the retort by means of a mechanism which is consequently obliged to pass through this material, is merely sustained or wedging between two jaws or two series of jaws arranged on each side at the base of the retort and adapted to project within the retort as two inclined surfaces in opposition to one another.

These jaws or groups of jaws are preferably located in hollow beams or boxgirders, situated beneath the separating piersbetween the retorts and supporting the weight of the whole superstructure of the retort; the jaws can be wholly withdrawn to the interior of these hollow beams to allow the discharge or drawing of the retort.

As a result ofthis arrangement, not only does the material remain absolutely intact but also the force to which the retaining mechanism is subjected acquires a much lower value. In fact the force is strictly limited to the pressure necessary. to retain the material acting as a wedge between the two jaws or groups of jaws, whereas in other arrangements the force required for traversely and therefore crushing the material may sometimes attain a very high value.

The attached sheet of drawings represents by way of example, one form of construction for carrying out the invention.

Figure 1 is a view in transverse section at the lower part of a battery of retorts; this figure shows on the right the arrangement of the jaws during the closure, and on the i left the position in whichthe jaws are withdrawn into a hollow beam during the fall of the material.

Specification of Letters Patent. I Patented Apr. 11, 1922- 1920. Serial No. 393,291.

Figure 2 is an external view in side eleyation of the mechanism for operating the aws.

Figure 3 is a view in axial longitudinal section at the bottom of the retort, affording a front view of one of the two series of jaws withdrawn into the centre of the hollow beam during the fall of the material.

At the bottom of the retort and on each side thereof, there are provided jaws consisting of cast-iron or steel plates a pivoting upon axes 6 carried in suitable bearings (not shown); these jaws face one another at the bottom of the retort and on each side thereof, below the brickwork piers or the like which separate the different retorts of the battery. 7

The jaws a are controlled by connecting rods 0 oscillating around axes d and operated by a shaft e by means of very short cranks f fixed upon this shaft and pivotally connected at g to the rods or links a.

The operating shaft e is carried in a number of bearings arranged in any suitable manner (not shown in the drawings).

All the bearings supporting the pivotal axes b of the jaws, as well as the operating shaft, may be secured upon a single longitudinal girder h. This girder, thus carrying all the operating mechanism, may be completely independent of the hollow beam or box-girder 71 within which the jaw a and its operating mechanism are enclosed; the hollow girder 71 supports the weight of all the brickwork and superstructure of the walls forming the retorts.

The movable girder h carrying the operating mechanism, is fixed within the hollow girder 2' by means of wedges h suitably arranged between the two.

The girder h is extended beyond the end of the retort at 7' (Figure 3) to form a seating for the speed-reducing gear which drives the main shaft 6; upon each of the shafts e is keyed a toothed wheel Z, meshing with a toothed wheel Z, keyed upon acountershaft parallel to the shaft e and carrying a worm wheel 70 meshing with a worm Z2; the shafts of the two worms k k dr1ving the main shafts e of a single retort, are coupled directly together and upon these shafts are keyed toothed wheels n meshing with pinions 0' carried by a common shaft 0 serving to operate the whole battery of retorts.

, The speed-reduction gears are arranged so that the two shafts e of a single retort revolve in opposite directions.

The hollow girder 71 upon its side facing the retort, presents a number of openings 1 for the passage of the movable jaws a, tnese openings being separated by fixed parts 9 of'dimensions sufficient to withstand the vertical load resting upon the girder z.

Each pier, that is to say, each dividing wall between two retorts is thus supported at its base by two hollow girders, allowing the accommodation of the retaining mechanism of two adjacent retorts. The end wall or pier of the battery need only be provided with a single hollow girder and operating mechanism.

What I claim is:

1. A discharging device for vertical continuous retorts comprisinga series of in- (lined metal jaws arranged side by side lengthwise of the depth of the furnace on each side at the bottom thereof, independent axes each having one of said jaws pivoted thereon, connecting rods, cranks, a horizontal shaft on each side of said furnace operating each of said jaws on that side of the furnace by meansof one of said connecting rods and one of said cranks, in combination with means located at the base of each furnace for transmitting to the said shafts opposite rotary movements so as to project said jaws into the interior of the retort and Wedge the material in the retort between the opposing jaws.

2. A discharging device for vertical continuous retorts having piers forming the side walls of the retort, a hollow beam fixed in the pier on each side of the retort chamber at the base and extending the length thereof and having openings in its face toward said retort chamber, a movable girder dnside each hollow beam, a shaft supported by each of said movable girders, short cranks wedged at intervals on' said shafts, links pivotally'connected to said cranks, inclined jaws pivotally joined to said links and aligned inside said hollow beams, independent axes on which said links pivot, in combination with means for transmitting to the said two shafts rotary movements in opposite directions so that the said inclined jaws are projected into the retort chamber and nace solely by wedging the same between the opposed jaws.

In testimony whereof I have signed myretain-the material at the base of the fur-
